A. Una onda armónica que se propaga por un medio unidimensional tiene una frecuencia de 500Hz y una velocidad de propagación de 350m/s. ¿Qué distancia mínima hay en un cierto instante, entre dos puntos del medio que oscilan con una diferencia de fase de π/3?

0.117 m

Explanation:

First of all, we can find the wavelength of the wave in the problem, by using the wave equation:

where:

v = 350 m/s is the speed of the wave

f = 500 Hz is the frequency of the wave

is the wavelength

Solving for ,

This means that the distance between two consecutive points of the wave having a difference of phase of

is 0.7 m.

Here we want to find the distance between two points that have a difference of phase of

So, we can set up the following rule of three:

where d' is the distance we are looking for. Solving for d',

this means that the temperature of both substances will be equal

radiation warms things up temp rises convection currents air circ windy weather
